HANS HANSEN, OF BREMEN, GERMANY.

MANUFACTURE OF INTERMEDIATE WALLS.

Specification of Letters Patent.

Patented May 5, 1908.

Application filed September 27, 1907. Serial No. 394,824.

To all whom it may concern:

Be it known that I, HANs HANsEN, a subject of the German Emperor, andresident of 28 Hamburgerstrasse, Bremen, Germany, have invented certainnew and useful Improvements in and Relating to the Manufacturing ofIntermediate Walls, of which the following is a specification.

The present invention relates to the manufacturing of intermediate wallsmade of plaster.

In the accompanying drawing in which I have illustrated my inventionlike letters of reference refer to like parts throughout the differentviews.

In said drawings, Figure 1 shows a front View, Fig. 2 shows a section onlines AA of Fig. 1. Fig. 3 shows another lever arrangement.

Two posts a, which are brought into a ver-- tical plane by means ofsupports 6 are placed opposite at a distance apart corresponding to thethickness of the wall to be built. Each post a is provided at certaindistances with pivotally mounted levers a, supported by bolts d. Thelevers c are provided with pro jections e. Furthermore pivotally mountedlevers g are placed on the vertical supports and provided withprojections These levers have handles h. The projections present a largesurface. The narrow levers c are guided in guides 2' located outside ofsaid levers.

The use of the apparatus is as described hereafter.

According to the length of the wall I erect several such pairs of postsand place at their lowest end two plates is, which stand opposite eachother at a distance corresponding to the oppositely located plate, Thelevers I are simultaneously turned around their bolts in order to placethe plate resting below against the projection e of the lever c, by theprojection f of the lever g into a vertical plane. In order to use thisapparatus for any desirable height I can compose the posts a of severalpieces, which as shown in Fig. 2 are mortised together and are kepttogether by bolts m. Instead of moving the plates 75 by hand I providerollers n on the upmost end of the post a and guide a cord 0 over thesame and connect it with the said plates. If one lever shall be spared Iuse the apparatus as illustrated in Fig. 3. In this last constructionthe lever c is provided with, besides the projection e, a sloping nose70. This nose effects in place of the second lever g the exact verticaladjustment of the plates. In order to prevent'a falling down of theplate this projection or nose p may engage a groove of the plate 75.

What I claim as new and desire to secure by United States Letters Patentis 1. In an apparatus for the manufacturing of intermediate walls thecombination of several vertical posts placed at the ends of the wall tobe built, long plates located at a distance apart corresponding to thethickness of the wall to be built and connecting said posts, levers (c)pivotally mounted on said posts, bolts (d) supporting said levers intheir horizontal position, means to lift the plates on all sides step bystep, means to turn saidlevers upward, and means to turn said leversdownward after the plates have passed the same, substantially asdescribed and for the purpose set forth.

2. In an apparatus for the manufacturing of intermediate walls thecombination of several vertical posts, long plates, levers (c), a guide,means to guide said levers in said guide, projections provided on saidlevers adapted to let the plate rest against the same, pivotally mountedlevers (g), handles rovided on said levers, projections of said evers(g) corresponding to the projections of the levers (c), substantially asdescribed and for the purpose set forth.

In testimony whereof I have hereunto signed my name this 14th day ofSeptember 1907, in the presence of two subscribing witnesses.
